Rewrite a better half of seshat

Move sessions to redisObject based for more flexibility
remove a lot of things
remove search and email utils for the time being
rename most controllers (all broken except maybe 500, 404 and index
mv flagr_core app
remove interface/templates as things are getting moved to mustache templates in view/mustache
add a few smaller files, fix links and general small things
update database gator and zmqgator a bit
remove service daemons as I'm going to rewrite them in a much better way
